Subject: [PATCH] Delay Chunk Unloads based on Player Movement
|
||
|
|
||
|
When players are moving in the world, doing things such as building or exploring,
|
||
|
they will commonly go back and forth in a small area. This causes a ton of chunk load
|
||
|
and unload activity on the edge chunks of their view distance.
|
||
|
|
||
|
A simple back and forth movement in 6 blocks could spam a chunk to thrash a
|
||
|
loading and unload cycle over and over again.
|
||
|
|
||
|
This is very wasteful. This system introduces a delay of inactivity on a chunk
|
||
|
before it actually unloads, which will be handled by the ticket expiry process.
|
||
|
|
||
|
This allows servers with smaller worlds who do less long distance exploring to stop
|
||
|
wasting cpu cycles on saving/unloading/reloading chunks repeatedly.
